Earlier in the week, Rob leaked his sister's phone number on social media because he was upset with his family for not inviting Blac Chyna to his baby shower.

I thought they weren't having Chyna at our baby shower. Chyna's baby shower is actually this Sunday, but they were trying to do a little surprise 'guy' baby shower for me and I was just upset trying to fight for Chyna like, 'Yo, she has to be at the baby shower. She's birthing my child. She needs to be there.' It was literally miscommunication and I probably shouldn't have went on Twitter, but I did.

In addition to sharing Kylie Jenner's number with the world, Rob posted an aggressive subtweet directed at his sisters.

TMZ recently reported Blac Chyna and Rob Kardashian have not been living together, which is what led the Kardashian sisters to throw separate baby showers for the couple -- one for Rob and a separate one for Chyna.

The source also said the reality stars haven't been speaking for months.
